Title: Method and device for chamfering plate material
Inventor: ISHIMURA KAZUHIKO
IPC: B24B49/02
Filed: 1991-09-09
Abstract: PURPOSE:To adjust position of a grinding wheel finely so that the dimensional accuracy of a plate glass, which is chamfered automatically without manual operation, exists in the range of an allowable error. CONSTITUTION:A roller 28 of a measuring means 12 is pressed to the polished surface of a plate glass 5, which is polished by a grinding wheel 52, to measure a displacement quantity of the roller 28 with a measuring means 12. A computing processing means 14 computes a dimension of the glass plate 5 on the basis of the measured displacement quantity of the roller 28, and in the case where the computed dimension of the plate glass 5 exceeds a preset threshold value, the computing processing means 14 computes a correction value for moving the grinding wheel 52 so as to set a dimension of the plate glass 5 at the preset threshold value or less. Furthermore, a grinding wheel moving means 16 moves the grinding wheel 52 on the basis of the correction value. Consequently, dimension accuracy of the chamfered plate glass 5 exists within the range of an allowable error.

Filed: 1993-09-14
Abstract: PURPOSE:To accurately obtain an RF power for bringing down a proton magnetization of water in a human body by 90 deg. by obtaining an NMR signal in which a signal from fat is restrained and by setting a point at which such an NMR signal becomes maximum to an optimum RF power. CONSTITUTION:An NMR signal from fat is obtained in an auto-power control by which an RF power necessary for bringing down a proton magnetization by 90 deg. is detected by using an MRI apparatus. This sequence is repeated while changing the RF power and a number of echo signals are obtained. The RF power when the echo signal becomes maximum is set as an optimum RF power, such an optimum RF power becomes the RF power for accurately bringing down the proton magnetization of water by 90 deg.. Thus, the optimum RF power can be obtained at a high precision.
